SYSTEM OF GAS DISTRIBUTION.

Application filed February 10, 1916.

To all whom t may concern.'

Be it known that I, ROBERT FRANCIS EL- DER, a citizen of the United States, residing at Lakeland, in the county of Jefferson and State of Kentucky, have invented new and useful Improvements in Systems of Gas Distribution, of which the following is a specification.

This invention relates to a system of gas distribution.

In establishments where numerous individual lires are in constant use, as in laundries, for heating sad irons, and in tin shops or canneries, for heating soldering irons and x etc., gas is extensively used.

Difficulty is encountered in the distribution of gas to the various points of consumption, economy in installation calling for pipe of minimum size while economy and efficiency in operation call for pipe of a size to supply a large volume of gas and of such size that the pressure will be substantially the same at all outlets. A compromise is generally effected by starting with a pipe of large diameter and reducing the size in proportion to the length.

In isolated plants, where gas is generated from liquid hydro-carbons, such as gasolene, an additional troublesome factor is introduced in the matter of condensation, the larger the pipe and the longer the run, the greater the condensation will be. The presence of condensation vapor in the gas, lowers its thermal efiiciency, and consequently the efiicieney of the heating system. The products of condensation may be trapped out of the pipe, but they are of no subsequent value in the production of gas.

An object of this invention is to provide a system of gas distribution whereby the burners may be fed by pipes of equal length each leading from a reservoir in which a constant pressure is maintained, thus insuring elieiency of consumption.

A further object is the provision of a system whereby with piping of minimum size and extent condensation is avoided, and gas delivered to the burners, at equal pressure.

The invention may be understood from a consideration of the following detailed description taken in connection with the accompanying drawing, which forms a part of the specification, with the understanding however, that while the drawing shows a f practical embodiment of the invention the Specification of Letters Patent.

Serial No. 77,362.

latter is by no means limited to exact conformlty therewith, but may be embodied in any other forms which come within the scope of the claim appended hereunto.

eferring now to the drawing which is a perspective View, wherein an embodiment of the invention is shown as in service in a laundry, the reference character -ldesignates a circular table around which a plurality of ironing boards -2- are grouped. A main supply pipe -3- rises from a gas generator -4L-, or other suitable source of supply, from the upper end of the riser 3, a lateral pipe -5- extends to a'point over the table. On the end of the lateral 5 is a fitting 6 from which a plurality of branches -7- extend. A plurality of pipes -8- depend respectively from the outer ends of each of the branches and from the body of the pipe 5 at a point removed from the fitting 6 a distance equal to the length of the branches 7 The drops 8 communicate with an annular equalizing, or distributing chamber -9-. The equalizing chamber is approximately of the same diameter as the table, and is suspended above and concentric therewith, it is preferably formed of pipe of the same size as the drops. From the equalizing chamber depend a plurality of feeder pipes -l0-, each having laterals 11k at their lower ends. From the ends of the laterale ll service pipes -12 lead to burners -l3 which are supported by the table, a burner being positioned in proximity to each of the ironing boards. A stop cock 14cis interposed in each service pipe. The main supply pipe is usually 2 inch pipe, the runner of 1% inch, the drops and equalizing chamber l inch, the feeders 10 of l inch, the laterals ll of inch, and the service pipes l2 of Si inch pipe. By my arrangement of grouping the heating devices, economy in installation is secured, owing to the small amount of piping required. By bringing the heating devices close to the generator, with consequent reduction in size and length of conduits, condensation is reduced to a minimum. By locating an equalizing chamber close to the burners they each receive gas at the same pressure and this can be regulated so that a maximum efliciency may be attained. Practice has demonstrated that with my improved system a saving of 50% may be attained over the old straight way system. A branch -15- leads oi to another unit similar to that just described.

Having thus described my invention 'so that anyone skilled in the art pertaining thereto may make and use the same, I claim: In combination a gas generator, a Work table, a distribution chamber suspended above said table and contoured to conform therewith, a plurality of burners positioned on the table, service pipe connecting said 10 burners With the distribution chamber, a supply pipe leading from the generator and a plurality of feeder pipes leading from a restricted area of the supply pipe to connections With the' distribution chamber at points 15 equi-distant in its circumference.
